Application filed June 25, 1918. Serial No. 241,849.

a citizen of the "United States, residing at,

Beaumont, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Shockers, of

which the following is a specification. I

This inventlon relates to grain Shockers.

One of the objects of this invention re sides in the provision of a shocker and capper which is automatic in operation.

Another object of this invention resides in the provision of a shocker and capper which automatically distributes the bundles to a compressor where it is capped and automatically discharged therefrom.

A still further object of this invention resides'in the provision of a shocker and capper which automatically compresses the shock and disposes it in an upright position prior to discharging it therefrom; A still further object of this invention resides in the provision of a shocker and cappe-r having an automatic compressor which is adapted to manipulate v certain means for preventmgthe del1very-oi bundies thereto during the" period it is dlschargingthe shock-therefrom.

A still further object of this inventionresides in the provision of a shocker and ca 3- per consisting of means for automatically compressing the shock and releasing it prior to delivering it to; theground.

With these and other objects in view this invention resides in certain novel features of construction, arrangement of parts, and combination of elements to he more particularly described in the specification herewith and pointed out in theappendedclaims, it being understood'that the right is reserved to resort to such changes in construction as. come within the scope otthe claims;

Inthe present embodiment ofthisinvention. the letter B in Fig. 2 designates a por- TO better setforth tho'operatioii ofthe struc' ture involved in thisiinvention, the binder herein illustrated is provided witli a shaft S which is manipulatedby the usual means employed for transmitting power jfrom-the which is suDP rted hyve'rtical standards 9 and inclined braces 10 that not only connect frame (i consisting of a superstructure 7' P the superstructure to the vtrance 6 but are inafter described.

.frame"6 consists of "substantially horizon tally disp'osed rails (1,?) and c, which together with railsgd e, and slats f form-what is herein termed-ahopper;

xtigidly secured to the braces 10 is an upwardly inclined platform 12 having a plurality of notches n'therein to receivethe Y sprocket wheels le which are supported on shafts 15 and 16 that are journaled adia cent the upper and lower ends of the inclined braces 10.

Trained over the sprocket'wheels 14' are conveyer chains 17 to which are pivotally secured at predetermined distances apart a plurality of teeth 18. The teeth 18 as herein disclosed are providedwithrunnere 19 utilized to support a conveyor 11 to be here which bear on the platform 12 during the elevation of the bundles and as soon as the bundles have reached an elevated position adjacent the upper sprocket wheels M, the

runners 19 will straddle the sprocket wheels whereupon the teeth will assume an inwardly inclined position to prevent their tendency to drag the bundles beneath the platform 12.

Suitably secured to the rail a of the hop per is a platform 20 having a plurality of slots 8 therein for the passage of the ends of grate fingers to be hereinafter set forth.

Rotatably supported by the rail a adjacent the inner and outer edges of the platform 20 are shafts 21 and 22 to which are splined or'otherwise fixedly secured a plurality of sprocket wheels 23 having trained thereover a plurality of conveyer chains 24 that carry a multiplicity of spaced teeth 25 for engagement with the bundles that are delivered from the inclined conveyer 11 to convey them to certain points beneath the platform 20.

Certain of the aforesaid shafts are preferably adjustable to permit the chains to be tightened and as common means heretofore employed will'be used they are omitted from the drawings. a

Journaled at its forward endin the rail r of the frame 6 is a wheel carriage 26 having a spindle 27 rigidly secured thereto for the reception of a wheel 28 to support the frame beyond its connection with'the binder frame. This wheel carriage is provided with means for adjusting the height of the shocker with that of the binder and since various adjusting means can be successfully employed to attain the desired results, a simple structure is herein disclosed which in volves the employment of a chain 30 fastened to the terminal 2f of the carriage and is adjustably connected to a hook it secured to one side of the frame 6, therefore it is apparent that as the chain is shortened. or lengthened. the carriage will either raise or lower the shocker frame.

Rigidly secured to said frame 6 is a laterally extending tubular hearing 31 which is for "ardly offset from the front rail p of the frame to receive a rotatable shaft 32. Secured to the inner end of the shaft 82 is a double crank arm 33, one end of which is connected to a link 34: that is pivoted to and manipulated by a similarlink fastened to a rod 35 that extends to the drivers seat where suitable levers (not shown) are provided for rocking the rod 35 and rotating the snaft 32.

Splined or otherwise secured to the outer end of the shaft 32 is a U-shaped bracketframe 40, which supports the trunnions ac,

on A

hinged sides ll and hinged shutters 42. In order to divide the inclosure formed by the hinged sides and the shutters in compartments, a plurality of partitions 43 are rin3- idly supported by the frame 40, said partitions being herein constructed in the form of open grates but any approved construction may be as successfully employed to are complish the initial functions of the grate.

Fixedly secured to the frame of the compressor are a plurality of runners 4r which are adapted to engage the ground and support the weight of the compressor during the period it is in its discharging position.

Each of the shutters is provided with cam shaped lugs 45 which are adapted to engage pins 46 carried by the frame 40 to retain the shutters in closed position while the compressor is being filled. To facilitate the manipulation of the shutters to permit the discharge of the shock from the compressor trips 4:? are hingedly secured to the frame 40 and extend in contact with the shutters as at 40 whereupon the shutters are lifted n t the tensionofsprings 40" upon the cement of the trips with the ground snock to hecompressed when these rollers are forced inwardly. One of the aforesaid shafts a9 is provided with a second crank 52 between which and one of the arms 3? of the U-shaned bracket 36 is hingedly secured an adjustable link 53 to facilitate the disengagement of the compressor cranks 5!) from the sides of the compressor during the descent of theU-shaped bracket 36 and the compressor. Since it is necessary to simul taneously actuate the connaressor cranks 5 to exert an inward pressure on opposite sides of the shock, the shafts 49 are provided with crank arms ii lthat are connected for ment in oppesite directions by links 55 which in turn are pivotally secured to the opposite ends of a rocker arm 56 that is journaled midway between the pivotal connections of links 55 as at 57. thus it will be seen that as one crank arm 5 is moved to compress the shock within the compressor, the other crank arm will similarly exerta like pressure for the reason that the rocker arm 5% will impart the proper motion thereto.

Secured to one ofthe crank one of the standards 9 of the strong retractile coil spring arms 54 and frame 6 is 58 which is a is sides of the compressor to permit the adapted to pull that arm to which it is con-- nected toward the standard 9 upon the actuation of a spring retained trip 59, that releases a catch as the guide roller 61 on the compressor frame assumes an elevated position prior to entering a guide 62 that is rigidly secured to the standards 9 for maintaining the compressor in an upright position while discharging the shock therefrom.

Adapted to tilt the compressor is a lever 63 which is pivotedas at 6d and is held in engagement with the roller 61 by a strong retractile coil spring 65, said coil spring being adapted to rock said lever 63 upon the release of the trip 66 by a cranked rod 67 which extends to suitable manipulating means (not shown) adjacent the seat of the driven Through the provision of the aforesaidlever 63 and coil spring .65 the compressor is tilted so that the shutters will assume a position to the rear of the shocker and upon the entrance of the roller 61 in the guide 62, the compressor will descend through the manipulation of ,the'shaft 32. As the shaft 32 is rotated to lower the compressor the lever 63' is returned to its normal position by an adjustable link 68 connectedas at 69 to the lower end of the double crank arm 33 and as at 70 to the lever 63. The link 68 is provided 'with a slot 71 at itsconnection 70 with the lever 63 to permitthespringto actuate the lever 63 without similarly exerting apulling action on the double crank arm 33.

Pivotally secured to the rails Z2 of thesuperstructure is an inner grate 72 having upwardly directed cranks 73 and 74 at the ends of its shaft 75 and a vertically disposed lug 76 adjacent the crank-73. Also pivotally supported by the rail 7) of the superstructure is an outer grate 77 having an upwardly directed crank 78 at the forward end of its shaft 78 and a downwardly directed crank 7 9 at the rear end of its shaft. This outer grate has its shaft provided with a crank arm 80 to which is pivotally connected a trip lever 81, that is provided with a bill 82 for engagement with the aforesaid lug 76 on the shaft 75 of the inner grate, therefore when the outer grate is rotated through the engagement ofrthe advanced bundle with the vertical fingers 83, the inner grate will be tilted upwardly and through the provision of coil springs 84 fastened to the cranks 73 and 78 the grates will remain tilted whereupon the progress of the next bundle will be interrupted by the upstanding fingers 85 of the inner grate and its weight will over balance the tension of the coil spring and cause the fingers 86 to assume their initial vertical position and the fingers 85 to assume their horizontal position as the bill 82 of the trip lever .81 previously disengaged the lug 7.6 on the shaft 75 so that-it was free to return without interference with the position of the outer grate, After the inner grate has discharged the bundle thereon, the'horizontal fingers of the inner grate form a platform for the passage thereover of the next proceeding bundle which encounters the ,upstanding (normally horizontal) fingers 87 of the outer grate and sincetheweight of this advancing bundle over-balances the tension of the coil spring 84, it willcause the horizontal (normally vertical) fingers S8 to tilt, whereupon the bundle like those previously mentioned will be deposited on pivoted traps 89 journaled in the rails 01 of the superstructure for delivery to the compressor. The resilient connections between the grates and traps are so disposed that upon rotating the cranks 73 and 78 beyond certain points, the springs will retain the grates in fixed position until interrupted by either the advancement of the bundles or their weight on their raised horizontal (normally vertical) fingers. a

The normally horizontal fingers of the grates and traps are retained in contact with their adjacent shafts by the exertion of. the coil springs on the cranks 73 and 78 therefore it is apparent that suitable stops are provided to limit their movement in one di rection.

The aforesaid trapsare provided to retain any bundles which are discharged from the grates during the period that the compressor is discharging the shock therefrom and in order to render the traps inoperative during this period, each shaft of the traps is provided with a lug 90 that is engaged by an adjustable notched latch bar 91 slidably supported by the forward standard 9 of the frame and having its lower end directed as at 92, in, the path of the U-shapedbracket 36, thus it is apparent that it is necessary to raise said compressor bracket before the latch bar will release the traps for manipulation. p

I Should the grates fail to automatically assume the proper positions for successfully discharging the capping bundle to the co npr'essors, manually manipulated means are provided with which the fingers of the grates can be adjusted to the desired positions. In producing a simple mechanism for attaining the above functions a slidable bar 93 is provided which has lugs 94 thereon for engagement with the cranks 74 and 79 and as these lugs are brought in contact with the cranks 74 and 79, the inner grateis directed to its normal position and the outer grate is'directed to a position to discharge the capping bundle therefrom on the trap be low where it is delivered to the center compartment of the compressors. Thismeans for manuallycontrolling the grates from the seat of the driver by a rope 95 is ofsuch construction that either grate can operate independently of the other, butcan be simultaneously manipulated to assume the proper working position.

To facilitate the return of the compressor to its normal position for receiving an additional supply of bundles after having discharged the shock, therein, leaf springs 96 are supplied. These leaf springs are of sufficient tension to overbalance the weight of the compressor when tilted and will readily return the compressor to its horizontal position as soon as the shock has been discharged therefrom.

In order to retain the sides of the compressor in their expanded positions after the compressor arms 50 are released, suitable springs 97 are fastened at one of their ends to the frame of the compressor with their opposite ends exerting an outward pressure against the side of the compressor to release the side pressure on the shock.

The shafts 16 and 21 are provided with meshing gear wheels 98 and 99 in order that the conveyor chains 2% will operate in the opposite direction to the conveyer 11 as the chain C rotates the shaft 16.

In operation thebundles of grain are deposited. on the conveyer 11 from the dischar e end of the binder and are elevated until engaged by the conveyer chains 24 whereupon the advanced bundle is conveyed to the outer grate and upon contacting with the fin ers 83 it will tilt the outer grate until its normally horizontal fingers 87 stand in an upright'position which manipu lation of the outer grate will cause the inner grate to similarly tilt by the action of the trip lever 81 on the lug 76, in which position they will remain under the influence of the coil springs 84. After the outer grate has assumed the aforesaid position the advanced bundle is discharged therefrom on to the trap 89 which deposits the advanced bundle in the outer compartment of the compressor. During the passage of the advance bundle from the grate to the compressor the upstanding (normally horizontal) fingers of the inner grate are encountered by the second bundle and since its weight over-balances the tension of the spring 84 it is deposited. on the trap therebelow where it is discharged to the inner compartment of the compressor. Now that the outer grate has its normally horizontal fingers disposed in an upright position with its normally vertical fingers 86 disposed in the position formerly occupied by the horizontal fingers 87, the third bundle is permitted to pass over the fingers 85 of the inner grate for they have been previously returned by the second bundle and upon abutting the up standing horizontal fingers of the outer grate, the third bundle will over-balance the spring 84 and cause the outer grate to tilt to its original position whereupon it vill be deposited on the trap beneath the outer grate from which. it will be delivered to the center compartment of the compressor.

After the compressor has been filled the rod 67 is rocked to release the trip 66 whereupon the coil spring will rock the lever 63 which through its engagement with the roller 61. will tilt the compressor in its bracket 37 until said roller strikes the trip 59 to release the catch 60, then the coil spring 58 causes the compressors 50 to exert an inward pressure on the sides of the compressor. After the compressor has been tilted and before it proceeds on its clownward course the outer grate discharges a bundle to the trap beneath from which it is deposited on the upstanding bundles yet to be discharged from the compressor to form the usual cap. In order to permit the de scent of the compressor the rod 35 is rocked to break the link connections 33 to the pivoted bracket and as the compressor descends, the compressors 50 are retracted by the links 53 and cranks 52 and upon the engagement of the hinged trips with the ground the shutters 42 are elevated to disengage their catches 4-5 whereupon the shutters will open and the shock will be discharged from the compressors During the period of time consumed to discharge the shock from the compressor the latch bar 91 will engage the lugs 90 of the traps and retain them in operative positions until the compressor is again returned for receiving the bundles.

After the shock has been discharged from the compressor the shutters 42 will be closed by the springs 40 and the compressor will return to its normal position under the influence of the springs 96 upon the roller being ejected from its guide by the manipulation of the bracket 36 through the instrumentality of the rod 35 and shaft 32, which is assisted in its return movement by a retractile spring 100. During the return of the compressor to its receiving position, the rocker arm 63 will be returned to its norman position and the latch bar 91. will be released from the lugs on the traps to render them operative until again locked by the descent of the compressor. With the compressor again in its receiving position each element will assume a position to be successfully manipulated to gain automatically form and discharge the shock with a cap thereon.
